Specification of Letters Patent.

Application filed June 21, 1902. Serial No. 112,684.

Patented. May 8, 1906.

To all whom it may concern:

Be it knownthat I, HENRY H. VAUGHAN, a citizen of the United States,residing at Cleveland, county of Cuyahoga, State of Ohio, have inventeda certain new and useful Improvement in Holders for Milling-Machines;and I declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit pertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

My invention relates generally to milling machines, and moreparticularly to mechanism for supporting the articles in position to beengaged by the cutters.

In the use of milling-machines for operating upon articles of a sizeless than the range 0 movement of the supporting-table relatively to thecuttersas, for instance, in the manufacture of channel-pins for unitingelectrical conductors-4t is desirable to support upon the table aplurality of rows of alined articles, the number in each rowcorresponding to the number of cutters in the gang and the number ofrows being determined by the extent of relative movement possiblebetween the table and the gang of cutters.

The object of my invention is to provide a milling-machine comprising agang of cutters and a relatively movable table upon which the articlesto be out are supported, with holding mechanism for receiving a numberof articles and retaining a plurality thereof in alinement with eachcutter of the gang, so that as the supporting-table and cutters arerelatively moved each cutter will engage in succession a plurality ofarticles, each reciprocation of the table relative to the cutters beingthereby utilized to out several articles, and consequently avoid thenecessity of returning the table to its initial position after a singlearticle has passed the corresponding cutter.

A further object of my invention is to provide the supporting-table of amilling-machine with means for removably holding one or more magazines,each of which is adapted to contain a plurality of articles to beengaged by the cutters.

'A still further object of my invention is to provide work-holdingmechanism of the character described for milling-machines, which will besimple in construction, inexpensive in manufacture, and efiicient inoperation.

My invention, generally described, consists in a holder adapted to besecured to the table of a milling-machine and having means for removablyretaining one or more magazines, each of which contains a plurality ofarticles spaced apart distances corresponding to the spaces between thecutters of the gang.

My invention will be more fully described hereinafter with reference tothe accompanying drawings, in which the same is illustrated as embodiedin a convenient and practical form, and in which Figure 1 is a sideelevational view of my improved holder and so much of a millingcutter asis necessary to show its connection therewith Fig. 2,, a plan view of myim proved holder and a portion of the table of a milling-cutter; Fig. 3,an elevational view looking from the left in Fig. 1; Fig. 4, anelevational View of one of the magazines; Fig. 5, a plan view of one ofthe magazines and Fig. 6, a cross-sectional view on line '6 6, Fig. 4.

Similar reference characters are used in the several figures of thedrawings to designate similar parts.

Reference-letter A indicates a shaft upon which are fixed one or morecutting-disks 6, b b b and b The cutting-disks are spaced apart by meansof collars a a", 0;, and a The shaft A is journaled upon suitablebearings, one of which is indicated at A at the right of Fig. 3. Thebearing A is shown as having a pointed end fitting within the recessformed in the reduced end a of the shaft. The cutters are spaced at thedesired distance from the o posite ends of the shaft A by means ofcollars a a interposed between the outside cutters of the series andnuts 0., screwed upon the ends of the shaft. The shaft .A may be rotatedin any preferred manner well known in the art of milling-cutters.

A'table C is supported upon the base of the machine and moved relativelyto the cutters in any well-known manner. The table C may conveniently beprovided with inwardlysite ends of the holder D. Nuts are secured uponthe ends of the bolts which extend above the flanges d and (Z and, ifdesired, washers may be interposed between theupper surfaces of theflanges and the nuts. The holder B is provided with a plurality ofchannels D, D and D extending parallel to the cuttersupporting shaft A.The channels are provided with overhanging flanges d to retain withinthe channels the magazines, subsequently to be described. The uppersurface of the holder D is provided with a se-. ries of parallel groovesg, g g g and 9 lo cated in alinement with the several cutters b, 860.Each of the channels D, D and D is adapted to receive a magazine F F FEach of the magazines is provided with a central channel F. The flangesformed at either side of'the channel F are provided with a series ofsockets to receive .the articles which are to be operated upon by thecutters.

In the present instance the recesses f, f f f and f 5 are so shaped asto receive U-shaped channel-pins which have been previously formed withthe desired exterior contour and which are to be engaged by the cutters,and thereby given the desired interior cross-section. In Fig. 2 themagazines F and F contain channel-pins which have not been engaged bythe cutters, while magazine F contains channel-pins which have beenoperated upon by the cutters. The magazines may be conveniently providedwithmeans, such as the eyes f, for inserting the same in and removingfrom the channels D, D and D formed in the holder D.

In order that the magazines may be so located in the channels in theholder that the grooves f, 850., may register with the grooves g, &c., astop is secured to the side of the holder opposite to that in which themagazines are inserted. This stop is shown as consisting in a cleat E,fastened to the holder by means of screws 6. The cleat is provided witha flange which projects above the channels D, D and D and is engaged bythe ends of the magazines when they are inserted in the channels. Themagazines are retained in engagement with the cleat E by latches E, Eand E These latches are shown as pro vided with openings near theirupper ends which surround screws 6 the heads of the latter extendingacross the openings in the latches, as clearly shown in Fig. 1.

Near the The number of channels to receive the 1 magazines may bevaried, the number only being limited by the extent of the relativemovement between the table and the gang of cutters. The number ofcutting-disks in the gang may also be varied, the maximum number beinglimited by the length of the shaft and by the width of the movabletable. The grooves g, &c., in the upper surface of the holder and thesockets f, &c., in the magae zines should of course correspond with thenumber of cutters and must obviously be spaced apart distancescorresponding to the spaces between thecutters.

The operation of my improvement, which will be readily understood. fromthe foregoing description, is as follows: The magazines before insertionin the holder are filled with channelpinsthat is, a channel-pin islocated. in each of the sockets f, f f f and f formed through theflanges at either side of the central passage F. The several latches E,E and E are slid downwardly, so as to permit the magazines to beinserted in the grooves D, D and D The magazines are prevented fromvertical displacement by the overhanging flanges (1. After the magazineshave been inserted in the holder the latches E, &c., are forced upwardlyaround the screws e so that the upper end of the latches engage the endsof the magazines. The setscrews e are then turned soas to engage thesurface of the holder, and thereby rock the latches about the heads ofthe screws 6 as fulcrums and force the magazines into contact with thecleat E. The relative location of the sockets in the magazines and thegrooves g, &c., in the holder is such that when the magazines areproperly secured within the channels in the holder the channel-pins willregister with the grooves g, &c. The table C is then moved relatively tothe rotating cutters, so that the channel-pins in the several magazinesare successively engaged by the corresponding cutting-disks. After thetable has completed its movement relatively to the gang of cutters it isreturned to the starting-point, where the magazines may be removed fromthe holder by unscrewing the set-screws e and permitting the latches E,&c., to drop below the path of movement of the magazines out of therespective channels in the holder. Other magazines, the sockets in whichhave been filled with channel-pins, are then inserted in the holder andlocked in place by means of the latches. The reciprocation of the table0 is then repeated and the channel-pins operated upon by the gang ofcutters;

From the foregoing description it will be observed that my improvementenables a number of articles to be successively engaged by each cutterof a gang, thereby utilizing a single reciprocation of the tablerelatively to the gang of cutters to cut a number of articles.

While I have described more or less precisely the details ofconstruction, I do not wish to be understood as limiting myself thereto,as I contemplate changes in form, the proportion of parts, and thesubstitution of equivalents as circumstances may suggest or renderexpedient without departing from the spirit of my invention.

Having now fullydescribed my invention, what I claim as new, and desireto secure by Letters Patent, is-

1. The combination with a multiple workholder for milling-machineshaving a channel therein extending transversely to the direction of itsmovement and also having a plurality of parallel grooves formed in theupper surface thereof and extending in the direction of movement of theholder, a magazine engaging said channel and adapted to support articlesin register with said grooves.

2. The combination with a multiple workholder having a channel extendingtransversely to its path of movement, of a magazine for removablyengaging said channel,

means for supporting a plurality of articles upon said magazine, a stopcarried by said holder at one end of said channel, and an adjustablelatch carried by said holder at the opposite end of the channel adaptedto engage said magazine and retain the same in contact with said stop.

3. The combination with a multiple workholder having a plurality ofchannels therein extending transversely to its direction of movement, aplurality of magazines engaging said channels and each adapted tosupport a plurality of articles, a stop carried by said holder at oneside thereof and projecting into alinement with said channels, and anadjustable latch carried by said holder at the end of each channelopposite to said stop, said latch being adapted to engage and re- 'tainthe corresponding magazine in contact with said stop.

In testimony whereof I sign this specification in the presence of twowitnesses.

HENRY H. VAUGHAN.
